Stormwater is runoff generated when rain (or the occasional snowmelt) flows over the ground.
Impervious surfaces like driveways, sidewalks, and streets prevent stormwater runoff from naturally soaking into the ground.
With roughly 50 inches of rain each year, the City proactively manages our stormwater through a series of 10,289 structures and 8,377 conveyances (pipes) that convey the stormwater into our streams, creeks, and ponds.
To get a better understanding of what the Stormwater Department oversees and manages, please read the Dunwoody Stormwater Extent of Service document.

Improving Water Quality
Stormwater is also very important as it relates to the quality of the water in our natural streams. As the stormwater flows over the streets, sidewalks, driveways, and parking lots it picks up and carries pollutants (like oil, lawn fertilizers, and litter) to our streams, creeks, and ponds. The City needs your help in order to improve our water quality and protect our natural water resources.
The City's Stormwater Management Plan provides details on all the Best Management Practices (BMPs) the City uses to be compliant with EPD's standards for municipal stormwater.
